More data NSFG for duration ergm sims
Model Params:
- proportion sexually debuted by age, sex
- time to relationship transition
Target Stats:
- mean rel lengths by reltype
- inst events rate (per year)
Q: at what point do we say everyone is eligible for relationships?
SOME WILL NEVER HAVE HETEROSEXUAL RELATIONS
Duration of relationship by type
mean of active relationships (where we assume exponential dist) plus estimates from survival analysis (using all reported relationships), exponential model fit
